Important features of LPC - 2129

Important features of LPC - 2129:
1. Comes in 64 pin package with 46 GPIO port pins.
2. 16KB of On-chip Static RAM to store Code &/or Data.
3. 256KB of flash memory.
4. External 8, 16, or 32 bit BUS.
5. ARM supports 1½ port concept.
6. On chip crystal oscillator 1 to 30MHz.
7. 60MHz max CPU clock available from programmable on chip PLL.
8. Supports ISP& IAP via boot loader.
9. Embedded ICE for real time debugging using break points and watch points.
10. Embedded Trace Macro cell ( Support of JTAG interface to debug the
program on the hardware level)
11. 2 CAN Controllers with Acceptance Filters.
12. 4 Channel 10 Bit ADC with conversion time of 2.44micro sec.
13. Two, 32 Bit Timers (4 capture and 4 compare channels).
14. PWM with 6 outputs.
15. RTC
16. 1 Watch Dog Timer.
17. Two UART’s.
18. Two SPI Interface.
19. Fast I2C at 400kbps.
20. Two low power modes IDLE and Power-Down mode.
21. CPU operating voltage +1.8V (1.65 to 1.95)
Peripherals operate at +3.3V (3.00 to 3.60)
I/O pins operate at +5V.
22. Supports ARM and THUMB mode.
23. Programming the flash memory can be done in the following ways.
1. Using serial JTAG interface
2. Using ISP & UART0.
3. Using IAP.
24. Supports 3 stage pipeline.
25. By default this supports LITTLE ENDIAN, but van be configured as BIG
ENDIAN.
